If I'm understanding your question/issue correctly...?   I ran into and issue when I installed the DrDiff offset shackles .He said there are two different sizes .  I'm lucky in that for me it just meant turning up new tube spacers on the lathe....

Center bolt is 5/16 with a 1/2 locator

GM used a 19/32 locator so allot of the replacement center bolts have the 19/32 locator so keep that in mind when sourcing your bolt..
